Abstract

A multivariable linear dynamic matrix control (DMC) strategy is implemented for a highly nonlinear, electrochemical process with significant dead time. The goal is for the control system to improve energy efficiency by returning the process to the desired operating point or to within control limits in an optimal manner. A comparison of the DMC strategy to traditional control strategies shows improved controller performance with DMC
